yes you will need a trunion, reciver flat (gunthings), and some time with a file or mill to remove the FA part of the bolt. there are prints on diffrent forms for the trunion and reciver. it is not a easy build but it can be done. most builds are now using reminton 870 fcg for easy 922r count. but some have tried the AK fcg and I have not found a " yes with a AK fcg" and working yet. muttman

I use AK fcg on my PPS-43 in 7.62 and 9x19 builds. However, AK FCG will not work with original lower. It's too high. I use AK- receiver as my lower. Also I use a tube instead of repair section from Wise Lite.

Easiest build is the PPS-43 bolt with Suomi barrel and drum. I can make it extremely reliable.

EDITED TO ADD:
You can only use double hook since you will have to cut off one of the trigger catch on the hammer since it interferes with the ejector/spring guide.

What about the barrel length? I thought they had to be 16 inches? Or is it okay if just the shroud is longer?

The barrel, unless registered as an SBR (US only, dependent on your state laws, etc, etc, etc.) must be at least 16" including any non-removable muzzle accessories. Non-removable means welded, blind pin, or hi temp silver solder (with a flow temp over 1125 F.) Otherwise you cannot legally have it... a barrel shroud does not count... not that Carolyn McCarthy would be able to tell the difference.

So in short, unless you get a tax stamp to make an SBR, you cannot assemble a PPS-43 as a rifle without a 16" barrel. You can however remove the underfolding stock or weld it in the closed position so that you in effect have a PPS-43 pistol.

Or just get some tubing that slip fits the barrel, and weld it on as an extension.
